Lower electrode dressing tool for projection welding

Abstract

A lower electrode dressing tool for projection welding machine is disclosed. The dresser includes a rotating cutting mechanism that includes multiple cutting elements. The rotating cutting mechanism has an opening and locating pin in the interior of the mechanism that seats and stabilizes a lower electrode of a projection welding machine against the dresser. While the dresser is in motion, the multiple cutting elements ride against and dress the flat upper surface of the lower electrode.

1 . A dresser for refurbishing a welding electrode, comprising: 
 a rotating cutting mechanism that comprises a plurality of cutting elements;    an opening within the interior of the cutting mechanism that seats the welding electrode against the cutting elements; and    a locating pin within the opening that contacts against the welding electrode to stabilize the rotating cutting mechanism.    
   
   
       2 . The dresser of  claim 1 , where the dresser is power by a pneumatic motor.  
   
   
       3 . The dresser of  claim 1 , where the dresser is a manual tool.  
   
   
       4 . The dresser of  claim 1 , where the dresser is a component of a projection welding machine.  
   
   
       5 . The dresser of  claim 4 , where the welding electrode comprises a locating hole that seats the locating pin of the dresser.  
   
   
       6 . The dresser of  claim 1 , where the rotating cutting mechanism comprises two cutting elements.  
   
   
       7 . The dresser of  claim 6 , where the two cutting elements are oriented at an angle of 120° with respect to each other.  
   
   
       8 . A dresser for refurbishing a welding electrode, comprising: 
 a rotating cutting mechanism that comprises a plurality of cutting elements;    means for seating the welding electrode against the cutting elements; and    means for stabilizing the rotating cutting mechanism against the welding electrode with a locating pin.    
   
   
       9 . The dresser of  claim 8 , further comprising: 
 means for seating the locating pin against the welding electrode with a locating hole in the welding electrode.
